Error, authentication is missing

[Carmelo Campos]

I am using sendmail.js with the source of opentrade, and I am registering my domain for mail.
I get the following error

mx resolved:

I don't know where to put the keys for smtp access

Send mail is used for direct mail ( Without a middle SMTP Server ), i think that you can better use nodemailer for what you're trying to do.

@CarmeloCampos I think @lacari3ff is spot on
